Abstract (en)
[origin: EP3917267A1] Embodiments of this application disclose an uplink transmission method and a communications apparatus, and relate to the communications field, so as to ensure that a terminal normally enters new transmission. The method includes: when transmitting, in a subframe in which an autonomous uplink transmission resource is configured, uplink data by using a first hybrid automatic repeat request HARQ process, considering that a new data indicator NDI for the first HARQ process is toggled, where the first HARQ process is a HARQ process that can be used for autonomous uplink transmission, and before the subframe, there is no uplink grant for the first HARQ process delivered to a HARQ entity; and performing new uplink data transmission in the subframe by using the first HARQ process.
